Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »

Chalmers researchers one step closer to using carbon fiber as a structural battery
Sweden’s Chalmers University of Technology has been experimenting with carbon fiber as a structural electrode. The team has studied the relationship between carbon fiber’s microstructure and electrochemical capacity, and is working to develop a combination that is both mechanically sound and energy dense. In short, they would like to use an EV’s body as its battery. The… Read more »
Are eVTOL companies starting a charging standards war?
Joby Aviation, a company developing electric vertical take-off and landing (eVTOL) aircraft for commercial passenger service, has announced a collaboration with Atlantic Aviation, a provider of aircraft ground handling and corporate flight support, to electrify aviation infrastructure in New York and Southern California, paving the way for the launch of Joby’s air taxi service. The… Read more »
eVTOL developers cooperate to deploy interoperable charging equipment for airports
In what appears to be an example of healthy coopetition, Archer Aviation has bought several multimodal chargers from rival eVTOL manufacturer Beta Technologies. Beta says it has delivered two chargers to Archer’s flight test facility in Salinas, California, where Archer is conducting a flight test campaign with its four-passenger Midnight eVTOL air taxi. Both Archer… Read more »
New studies indicate that battery-electric aircraft with 800 km range could be practical
Several companies are working on battery-electric aircraft, but electric aviation is a tougher nut to crack than electric cars, for physical reasons. It simply takes a lot more energy to keep an aircraft aloft than it does to propel a vehicle along a road, and every additional pound of battery weight takes a steep toll… Read more »
Argonne collaborates with NUMiX Materials on battery recycling and biofuel research
Researchers at the DOE’s Argonne National Laboratory have collaborated with sorbent development company NUMiX Materials to investigate the use of a process called capacitive deionization to recycle automotive batteries and produce biofuel. Capacitive deionization separates nickel, manganese and cobalt from other battery materials by relying on their electrical charges. According to Argonne Environmental Engineer Lauren… Read more »
ABB to provide charging infrastructure for Lilium’s electric regional air network
ABB E-mobility will provide the charging infrastructure for electric aircraft manufacturer Lilium‘s regional air network, which is scheduled for commercial launch in 2024. Lilium has announced planned launch networks in Florida, Germany and Brazil. As part of the agreement, ABB will develop, test and supply charging equipment based on standards being developed by CharIN’s Megawatt… Read more »
University of Illinois puts hybrid aircraft to the test in simulation
Automobiles are trending towards electric power – but what about their counterparts in the sky? Jet fuel and aviation gasoline are very energy-inefficient, but they have one big advantage: they’re lightweight. Every gram matters in the aerospace industry. That’s why electrifying an aircraft is so difficult: although batteries would be much more efficient than jet… Read more »
Alvant’s aluminum matrix composites boast 40% weight savings for electric motor rotors
Innovate UK is sponsoring a number of competitions to spur companies to develop emissions-reducing vehicle technologies, with millions of pound in grant money for the winners. One of these is Make it Lighter with Less, which aims to improve the efficiency and performance of electric motors. This project is led by Alvant, a specialist in… Read more »
Experimental NASA airplane features 14 propellers driven by 14 electric motors
NASA is building an experimental airplane in order to demonstrate that electric propulsion can make planes quieter, more efficient and more environmentally friendly. The X-57, nicknamed “Maxwell,” has 14 electric motors turning 14 propellers, integrated into a specially-designed wing. NASA Aeronautics researchers hope to use Maxwell to validate the idea that distributing electric power across… Read more »
